F=BIL Or is it….. F=qvB Also Determine the direction of the Force!
V B Positive Charge is moving
Use: F=qvB Force is going:
V B Negative Charge is moving
Use: F=qvB Force is going: Coming out of the page!
B I
Use: F=BiL Force is going:
F = 1.5x10-12 N V = 2.0x107 m/s Electron B = ?
Use: F=qvB 1.5 x 10-12= (1.6 x 10-19C) x (2.0x107 m/s) x B B= .46875 T Force is going:
B = .15 T Electron V = 1.5x106 m/s F = ?
You would break your hand trying this one so the charge will not feel any force
What is the acceleration of the proton? Mass of a proton is = 1.67262158 × 10-27 kilograms B = .75 T Proton V = 5.8x106m/s
Use: F=qvB F=ma ma=qvB (1.67262158 × 10-27 kg)x a = (1.6 x 10-19C) x (5.8x106m/s) x .75 T a = 4.167 x 1014 m/s/s Force is going:
1. What is the acceleration of the electron? B = .75 T 2. What is the radius of curvature? Hint: ac = v2/r Electron V = 4.5x107m/s
Use: F=qvB F=mv2/r mv2/r=qvB (9.11 × 10-31 kg)(4.5x107m/s)2/r= (1.6 x 10-19C) x (4.5x107m/s) x .75 T r = 3.4 x 10-4 m Force is going:
